' HEEL-BREAST-SHANK-SANDING,DEVICE.

Application filed. July 1,

To all whom it may concern: u

Be it known that I, .Gnonen R. ELLIs, a citizen of the United States of America, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in I-Ieel- Breast-Shank-Sanding Devices, of which the following is a specification.

Devices heretoforein use for sanding the shank of a shoe, have been of a construction such that they left untouched a portion of the shank adjacent to the heel breast. This untouched portion had then to be finished by hand operations.

An object of my invention is to produce a heel breast shank sanding device in which the necessity of hand operations at this portion of a shoe construction is overcome and in which all but those portions of a shoe it is desired to sand, are protected from injurious contact with any moving elements of the device.

This and other objects are attained in the device described in the following specification and illustrated in the accompanying drawing in which;-

Fig. 1, is a side elevation of a sanding device embodying my invention and of a heel being operated upon thereby.

Figure 2 is a view of the device looking in the direction of arrow A in Figure 1.

Figure 3 is a sectional view of the device, on the line 3--3 of Figure 2.

Fig. i is a sectional view on line X-X of Fi 1.

Fly sanding device comprises a rotary spindle 6-10, which is of a length less than the distance between the top lift a and the heel breast shank b of the shoe, a mounting device 1 1-18 adapted to support the spindle within the space between the heel breast d and the heel breast shank b of the shoe, a grinding disc 8-9, and a means for rotating the spindle.

I will now describe the parts of my device in detail.

Within housing 4., a large bevel gear 5 is rotatively mounted by means of a screw 6 which has hearing within the housing and rotates with the gear. A disc-like flange 7 extending from the gear, closes housing 4 and aflords a backing for a soft rubber disc 9 upon which discs of sand or emery paper 8 are removably mounted by means of a screw 10. A cooperating gear or pinion 11 is also mounted in the housing in mesh with Specification of Letters late nt.

gear 5', ashaft 12 mounting gear 11 and being ournalled in an elongated bushing 13 screwed into an extensionli of housing 1 of the device as'shown in Figure 3. By means of this construction the shaft to which gear 11 is secured, isheld in position, the hub 15 of the gear engaging the end of the bushing. A pulley 16 is secured to shaft 12 beyond the bushing, for receiving a belt 17 which drives the device. To secure the device in convenient positions to operate upon a shoe, I have provided a clamping sleeve 18 from which a pin 19 extends to be attached to a suitable support.

I In using my improved sanding device it is preferably secured in the position shown in F igure 1, a disc of sand or emery paper 8 having been secured upon the rubber disc 9 by means of the screw 10. The disc is then rotated whilst the shoe to be operated upon is held in the position shown in Figure l to bring the edge of the sanding disc well into the juncture of the breast and shank of the shoe, thus sanding that portion of the bottom of the shoe, not reached by the separa breast and shank sanding machines now use. This saves the necessity of having to resort to the usual hand operation of finishing the untouched portion of the bottom of the shoe.

Having thus described my invention, what I claim is 1. A sanding device for the heel breast shanks of shoes consisting of a housing of a depth less than the distance between the top lifts and the heel breast shanks of the shoes, a gear rotatably mounted within the housing, a flange formed integral with the gear and projecting beyond the edges of the housing and forming a cover for the gear hous- Patented Feb. 1 4., 19212.

ing, a yielding disc secured adjacent the gear, means adapted to retain an abrasive disc upon the yielding disc, a second gear within the housing and meshing with the first mentioned gear at an angle thereto, a shaft secured to and adapted to drive the second mentioned gear and a bushing secured to the housing and adapted to retain the second mentioned gear within the housmg.

2. A. sanding device for the heel breast shanks of shoes, consisting of an open sided housing, a gear rotatively mounted partly within the housing and having a flange forming a cover on the open side of the housing, a yielding disc mounted against the obtuse angle to the axis of said spindle, means carried by said shaft and being adapted to rotate said spindle, a grinding disk carried by the spindle and all of which in combination being adapted to enter the angle 20 between the heel breast shank and the heel breast ofa shoe.

In testimony whereof, I have hereunto subscribed my name this 28th day of June, 1918.
